What Is the Deadline to File State Taxes?
The deadline to file state taxes varies by state. Many states have a due date that is similar to the federal date and other states have a later deadline to file state taxes. Of course, there are a few states that have no personal income tax, so there are no due dates to consider.
You should check with your state revenue department to confirm the due date for taxes each year. Keep in mind, the deadline may shift annually due to weekends and holidays.
State Tax Return Deadline – Can I File My State Return Later?
You can file your state return after your federal return as long as it is filed before your state tax return deadline. However, you will not be able to e-file your state return if you mailed your federal return first. You can file your state and federal tax returns at any point before the filing deadline.
